  <background>
    <p>Squashfs is a compressed read-only filesystem for Linux. Squashfs is
      intended for general read-only filesystem use, for archival use (i.e. in
      cases where a .tar.gz file may be used), and in constrained block
      device/memory systems (e.g. embedded systems) where low overhead is
      needed.
    </p>

  <description>
    <p>Multiple vulnerabilities have been discovered in SQUASHFS. Please review
      the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted .sqsh
      file using unsquashfs; possibly resulting in the execution of arbitrary
      code with the privileges of the process, or a Denial of Service
      condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All squashfs-tools users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-fs/squashfs-tools-4.3"
    </code>
